2 Claims.

This invention relates to new and useful improvements in light fixturesand it is among the objects thereof to provide a safety type of glassholder and socket cover for enclosing light globes.

A further object of the invention is to provide a glass holder andsocket cover adapted to diffuse light wherein the top and bottomportions of the unit are of glass of different characteristics andwherein the fitting of the parts produce a semi-indirect or asemi-direct lighting effect.

It is a further object of the invention to providea light fixture of theabove-designated character which shall largely eliminate the use ofmetal parts, and thereby produce a lighting unit in which no dark andlight areas aresharply contrasted.

The invention will become more apparent from a consideration of theaccompanying drawing constituting a part hereof in which like referencecharacters designate like parts and in which:

Fig. 1 is a bottom plan view partially in crosssection of a light unitembodying the principles of this invention;

Fig. 2 a front elevational view partially cut away to illustrate theinterior and cross-section of the parts of the structure shown in Fig.1;and

Fig. 3 a front elevational view of the light unit suspended by a ceilingsupport.

In the drawing, the numeral I designates a rod having a threaded end 2from which it is suspended from a canopy which may be of glass, andhaving a threaded end 2" to which is secured a light socket 3 ofporcelain or metal and whichis provided with a washer l forming anabutment for a combined socket cover and fixture support designated bythe numeral 5.

The inner surface of the socket cover or fixture support 5 is providedwith longitudinal ribs 6 and the outer surface on the shank portion isprovided with longitudinal ribs 1 to provide diffusion of light, theelement 5 being made of crystal glass.

A plurality of lugs 8 having shoulders 9 are formed in angularly spacedrelation around the outer surface of the member 5 to receive a cover 10provided with outer ribs II and inner ribs I2 for diffusion of light.The bottom of the socket cover is of substantially elliptical shapeterminating in fianges I3 which is adapted to be inserted in acylindrical opening ll of the light fixture which is made of opal glassor the like and which is provided with a constricted neck portion thatrests upon the shoulder 16 formed by the flange IS, the fixture beingdesignated by the numeral I1 and when suspended in position has theappearance of Fig. 3, the shape of the fixture I! being optional.

As herein illustrated and described, a lighting unit is of the screwlessor safety type and is constructed of all glass parts. Thesocket-enclosing portion 5 is of crystal glass frosted, and the bottomhalf being of an opaque glass; however, the parts may all be made fromopal glasses in either white or ivory or any desirable color.

As appears from the drawing, the light is diffused through the socketcover and the globe holder, and sufficient light is emitted between thespace of the members 5 and II between the lugs 8 to produce an indirectlighting efiect. The entire structure is made of glass and eliminatesthe contrast between metal and glass which is a great improvement overthe metal type globe holders.

By ribbing both the inside and outside of the socket cover, the socketand fixture of wiring parts are not visible. The cover l0 eliminatesadmission of dust to the fixture I1 and produces no strain on thefixture as it primarily rests on the shoulders 9 of the socket cover.

Although one embodiment of the invention has modifications may be madein the details of construction without departing from the principlesherein set forth.

I claim:

1. A screwless safety type glass holder and socket cover for .enclosingglobes comprising a socket cover having vertical inner and horizontallydisposed outer diffusing ribs and having angularly spaced lugs,- saidsocket cover having a fiared bottom of substantially elliptical shapefor insertion through the opening of a glass fixture, a glass fixturehaving a circular neck portion seating on the flared bottom of saidsocket cover and a glass cover resting on said lugs and covering theneck portion of the fixture, said last mentioned cover having inner andouter ribs similar to the ribs of the socket cover.

2. A screwless safety type glass holder and socket cover for enclosingglobes comprising a socket cover having inner and outer diffusion ribsand having an elliptically shaped fiange portion at the bottom thereof,a light fixture suspended from and supported by the elliptical fiangesof said socket cover, said socket cover having angularly spaced lugs, aglass cover supported by saidlugs having a depending flange out ofcontact with the light fixture, the last named cover being spaced fromthe fixture and the socket cover to provide ventilation and lightopenings therein.
